[Technical Field]
[0001] The disclosure relates to an electronic device including a three-dimensional (3D) display that displays a 3D screen, and a method for operating the same.
[Background Art]
[0002] The development of technology for electronic devices has led to the widespread use of various types of electronic devices, such as mobile communication terminals, personal digital assistants (PDAs), electronic notebooks, smartphones, tablet personal computers (PCs), and wearable devices.
[0003] For example, an electronic device focuses on enabling a viewer to watch an image where a stereoscopic effect is implemented from a free position without the hassle of wearing glasses, beyond the limitations of the existing 3D stereoscopic imaging scheme which requires wearing glasses. A 3D display that displays glasses-free 3D stereoscopic images is implemented by fusing multi-viewpoint images into one, which provides different images to the left and right eyes using a viewer's eye parallax to achieve the stereoscopic effect.
[0004] Further, for example, an electronic device may provide virtual reality (VR), which allows a user to have a real-life experience in a virtual world created by a computer, augmented reality (AR), which displays virtual information (or objects) added to the real world, and mixed reality (MR), which is a blend of VR and AR. The electronic device provides the user with 3D stereoscopic images corresponding to VR, AR, or MR.
[0005] The above information is presented as related art only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.

[0013] FIG. 1 is a block diagram illustrating an electronic device 101 in a network environment 100 according to an embodiment of the disclosure.
[0014] Referring to FIG. 1, the electronic device 101 in the network environment 100 may communicate with an electronic device 102 via a first network 198 (e.g., a short-range wireless communication network), or at least one of an electronic device 104 or a server 108 via a second network 199 (e.g., a long-range wireless communication network). According to an embodiment, the electronic device 101 may communicate with the electronic device 104 via the server 108. According to an embodiment, the electronic device 101 may include a processor 120, memory 130, an input module 150, a sound output module 155, a display module 160, an audio module 170, a sensor module 176, an interface 177, a connecting terminal 178, a haptic module 179, a camera module 180, a power management module 188, a battery 189, a communication module 190, a subscriber identification module (SIM) 196, or an antenna module 197. In some embodiments, at least one of the components (e.g., the connecting terminal 178) may be omitted from the electronic device 101, or one or more other components may be added in the electronic device 101. In some embodiments, some of the components (e.g., the sensor module 176, the camera module 180, or the antenna module 197) may be implemented as a single component (e.g., the display module 160).
[0015] The processor 120 may execute, for example, software (e.g., a program 140) to control at least one other component (e.g., a hardware or software component) of the electronic device 101 coupled with the processor 120, and may perform various data processing or computation. According to an embodiment, as at least part of the data processing or computation, the processor 120 may store a command or data received from another component (e.g., the sensor module 176 or the communication module 190) in volatile memory 132, process the command or the data stored in the volatile memory 132, and store resulting data in non-volatile memory 134. According to an embodiment, the processor 120 may include a main processor 121 (e.g., a central processing unit (CPU) or an application processor (AP)), or an auxiliary processor 123 (e.g., a graphics processing unit (GPU), a neural processing unit (NPU), an image signal processor (ISP), a sensor hub processor, or a communication processor (CP)) that is operable independently from, or in conjunction with, the main processor 121. For example, when the electronic device 101 includes the main processor 121 and the auxiliary processor 123, the auxiliary processor 123 may be adapted to consume less power than the main processor 121, or to be specific to a specified function. The auxiliary processor 123 may be implemented as separate from, or as part of the main processor 121.
[0016] The auxiliary processor 123 may control at least some of functions or states related to at least one component (e.g., the display module 160, the sensor module 176, or the communication module 190) among the components of the electronic device 101, instead of the main processor 121 while the main processor 121 is in an inactive (e.g., sleep) state, or together with the main processor 121 while the main processor 121 is in an active state (e.g., executing an application). According to an embodiment, the auxiliary processor 123 (e.g., an image signal processor or a communication processor) may be implemented as part of another component (e.g., the camera module 180 or the communication module 190) functionally related to the auxiliary processor 123. According to an embodiment, the auxiliary processor 123 (e.g., the neural processing unit) may include a hardware structure specified for artificial intelligence model processing. An artificial intelligence model may be generated by machine learning. Such learning may be performed, e.g., by the electronic device 101 where the artificial intelligence is performed or via a separate server (e.g., the server 108).

The speaker may be used for general purposes, such as playing multimedia or playing record. The receiver may be used for receiving incoming calls. According to an embodiment, the receiver may be implemented as separate from, or as part of the speaker.
[0021] The display module 160 may visually provide information to the outside (e.g., a user) of the electronic device 101. The display module 160 may include, for example, a display, a hologram device, or a projector and control circuitry to control a corresponding one of the display, hologram device, and projector. According to an embodiment, the display module 160 may include a touch sensor adapted to detect a touch, or a pressure sensor adapted to measure the strength of force incurred by the touch.
[0022] The audio module 170 may convert a sound into an electrical signal and vice versa. According to an embodiment, the audio module 170 may obtain the sound via the input module 150, or output the sound via the sound output module 155 or a headphone of an external electronic device (e.g., an electronic device 102) directly (e.g., wiredly) or wirelessly coupled with the electronic device 101.
[0023] The sensor module 176 may detect an operational state (e.g., power or temperature) of the electronic device 101 or an environmental state (e.g., a state of a user) external to the electronic device 101, and then generate an electrical signal or data value corresponding to the detected state. According to an embodiment, the sensor module 176 may include, for example, a gesture sensor, a gyro sensor, an atmospheric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.
[0024] The interface 177 may support one or more specified protocols to be used for the electronic device 101 to be coupled with the external electronic device (e.g., the electronic device 102) directly (e.g., wiredly) or wirelessly. According to an embodiment, the interface 177 may include, for example, a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, a secure digital (SD) card interface, or an audio interface.
[0025] A connecting terminal 178 may include a connector via which the electronic device 101 may be physically connected with the external electronic device (e.g., the electronic device 102). According to an embodiment, the connecting terminal 178 may include, for example, a HDMI connector, a USB connector, a SD card connector, or an audio connector (e.g., a headphone connector).
[0026] The haptic module 179 may convert an electrical signal into a mechanical stimulus (e.g., a vibration or a movement) or electrical stimulus which may be recognized by a user via his tactile sensation or kinesthetic sensation. According to an embodiment, the haptic module 179 may include, for example, a motor, a piezoelectric element, or an electric stimulator.

[0030] The communication module 190 may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and the external electronic device (e.g., the electronic device 102, the electronic device 104, or the server 108) and performing communication via the established communication channel. The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.
[0031] The wireless communication module 192 may support a 5G network, after a 4G network, and next-generation communication technology, e.g., new radio (NR) access technology. The NR access technology may support enhanced mobile broadband (eMBB), massive machine type communications (mMTC), or ultra-reliable and low-latency communications (URLLC). The wireless communication module 192 may support a high-frequency band (e.g., the mmWave band) to achieve, e.g., a high data transmission rate. The wireless communication module 192 may support various technologies for securing performance on a high-frequency band, such as, e.g., beamforming, massive multiple-input and multiple-output (massive MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module 192 may support various requirements specified in the electronic device 101, an external electronic device (e.g., the electronic device 104), or a network system (e.g., the second network 199). According to an embodiment, the wireless communication module 192 may support a peak data rate (e.g., 20Gbps or more) for implementing eMBB, loss coverage (e.g., 164dB or less) for implementing mMTC, or U-plane latency (e.g., 0.5ms or less for each of downlink (DL) and uplink (UL), or a round trip of 1ms or less) for implementing URLLC.

In such a case, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network 198 or the second network 199, may be selected, for example, by the communication module 190 (e.g., the wireless communication module 192) from the plurality of antennas. The signal or the power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 197.
[0033] According to an embodiment, the antenna module 197 may form an mmWave antenna module. According to an embodiment, the mmWave antenna module may include a printed circuit board, a RFIC disposed on a first surface (e.g., the bottom surface) of the printed circuit board, or adjacent to the first surface and capable of supporting a designated high-frequency band (e.g., the mmWave band), and a plurality of antennas (e.g., array antennas) disposed on a second surface (e.g., the top or a side surface) of the printed circuit board, or adjacent to the second surface and capable of transmitting or receiving signals of the designated high-frequency band.
[0034] At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).
[0035] According to an embodiment, commands or data may be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 coupled with the second network 199. Each of the electronic devices 102 or 104 may be a device of a same type as, or a different type, from the electronic device 101. According to an embodiment, all or some of operations to be executed at the electronic device 101 may be executed at one or more of the external electronic devices 102, 104, or 108. For example, if the electronic device 101 should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 101, instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device 101. The electronic device 101 may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device 101 may provide ultra low-latency services using, e.g., distributed computing or mobile edge computing. In another embodiment, the external electronic device 104 may include an internet-of-things (IoT) device. The server 108 may be an intelligent server using machine learning and/or a neural network. According to an embodiment, the external electronic device 104 or the server 108 may be included in the second network 199. The electronic device 101 may be applied to intelligent services (e.g., smart home, smart city, smart car, or healthcare) based on 5G communication technology or IoT-related technology.

[0044] In an embodiment, the eye-tracking sensor 240 may be an image sensor that directly senses the position of the user's eye (e.g., left and right eyes). In an embodiment, the eye-tracking sensor 240 may be a position sensor that detects the position of the user's face, and the processor 210 may estimate the position of the user's eye based on the detected position of the user's face.
[0045] The input interface 250 according to an embodiment may receive a user input corresponding to a 3D screen displayed on the 3D display 230. In an embodiment, the input interface 250 may receive an indirect operation input via an input device 105 connected to the electronic device 101 or a direct operation input of the user obtained through a sensor (e.g., the touch panel 260 or the camera sensor 270). In an embodiment, the input interface 250 may support a designated protocol for connection to the external input device 105.
[0046] The touch panel 260 according to an embodiment may be integrally coupled to the 3D display 230 and sense a touch input of the user corresponding to a 3D screen displayed on the 3D display 230. In an embodiment, the electronic device 101 may display a controller (e.g., a slider or coordinates) in at least a partial area of the 3D display 230 and sense a touch input of the user corresponding to the displayed controller. For example, the touch panel 260 may sense a touch based on principles such as a capacitive scheme, an electromagnetic scheme, a pressure method, or an IR scheme, to which the disclosure is not limited.
[0047] In an embodiment, in addition to a physical contact touch of the user, the touch panel 260 may sense a proximity touch that approaches or is in close proximity to the touch panel without mechanical contact. For example, the touch panel 260 may sense a proximity touch based on principles such as a transmissive photoelectric sensor, a direct reflective photoelectric sensor, a mirror reflective photoelectric sensor, a high-frequency oscillation-type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, or an IR proximity sensor, to which the disclosure is not limited.
[0048] In an embodiment, when the touch panel 260 uses the capacitive scheme, it may detect a proximity touch of a pointer based on a change in an electric field caused by the proximity of the pointer, as well as a contact touch of the user.
[0049] The camera sensor 270 according to an embodiment may sense a user gesture occurring in front of the 3D display 230. In an embodiment, a gesture by the user's hand may occur in front of the 3D display 230 to correspond to a 3D screen on the 3D display 230, and the camera sensor 270 may sense the position and type of the user gesture.
[0050] The input device 105 according to an embodiment may be connected to the electronic device 101 wiredly or wirelessly. For example, the input device 105 may be a stylus pen or controller that transmits an operation input according to a slider or coordinates. For example, the input device 105 may obtain an input such as a movement, a touch, a button click, or hovering, and provide a signal corresponding to the obtained input to the electronic device 101 (e.g., the input interface 250).
[0051] The electronic device 101 according to an embodiment may move, enlarge, or change a 3D screen (or object) displayed on the 3D display 230 based on a user input obtained from the input interface 250 connected to the touch panel 260 or the camera sensor 270, or from the external input device 101.
[0052] FIG. 3A illustrates screens provided respectively to the user's left eye L and right eye R according to a left/right split scheme, according to an embodiment of the disclosure. FIG. 3B illustrates a screen perceived by the user according to the displayed screens of FIG. 3A. FIG. 4 illustrates objects (a 2D image and a 3D image) corresponding to various sense of depth, included in a 3D screen according to an embodiment of the disclosure.
[0053] Referring to FIGS. 3A, 3B, and 4, the electronic device 101 according to an embodiment may provide a 3D screen through the 3D display (e.g., the 3D display 230 of FIG. 2) according to a left/right split scheme using binocular parallax. In an embodiment, the electronic device 101 may use a left/right split scheme that displays differently an image (L image) provided to the user's left eye L and an image (R image) provided to the user's right eye R, so that the user perceives a 3D screen. The human brain may observe a 3D image by synthesizing an image (L image) viewed through the left eye L and an image (R image) viewed through the right eye R.
[0054] In an embodiment, the electronic device 101 may control a user-felt sense of depth of an object (a 2D image or a 3D image) included in a 3D screen by adjusting a relative position and distance between an image (L image) corresponding to the left eye L and an image (R image) corresponding to the right eye R.
[0055] In an embodiment, the electronic device 101 may display the image (L image) corresponding to the left eye L and the image (R image) corresponding to the right eye R identically, thereby displaying the 3D screen, so that the user perceives the 2D object (2D image) as having a sense of depth corresponding to a display area 235 of the 3D display 230.
[0056] In an embodiment, the electronic device 101 may display a 3D screen by moving an image (L image) corresponding to the left eye L to the left and moving an image (R image) corresponding to the right eye R to the right, so that the user perceives a 3D object (3D image) as having a sense of depth of being located backward in the display area 235 of the 3D display 230.
[0057] In an embodiment, the electronic device 101 may display a 3D screen by moving an image (L image) corresponding to the left eye L to the right and moving an image (R image) corresponding to the right eye R to the left, so that the user perceives a 3D object (3D image) as having a sense of depth of being located forward in the display area 235 of the 3D display 230.
[0058] FIG. 5A illustrates a method using a lenticular lens 510 according to an embodiment of the disclosure. FIG. 5B illustrates a method using a parallax barrier 520 according to an embodiment of the disclosure.
[0059] Referring to FIGS. 5A and 5B, the electronic device 101 may generate binocular parallax between the user's left eye L and right eye R to provide a 3D screen according to a left/right split scheme.
[0060] Binocular parallax (stereo disparity) refers to the difference in the perspective with which a person's left eye L and right eye R view an object. When the human brain synthesizes an image viewed through the left eye L and an image viewed through the right eye R, the synthesized image gives the person a sense of depth. 3D image display methods based on binocular parallax may be categorized into a glasses type that requires special glasses and a glasses-free type that does not require glasses.
[0061] The glasses type includes, for example, a method using color glasses with wavelength selectivity, a polarization glasses method using a light-blocking effect due to a polarization difference, and a time-division glasses method that alternately presents left and right images within the persistence of vision of the eye. In addition, there is a method of obtaining a sense of depth for movement in the left/right direction based on a time difference in the visual system resulting from a difference in transmittance by attaching filters with different transmittances to the left and right eyes L and R, respectively.
[0062] The glasses-free type, which is a method of generating a sense of depth on an image display surface side, rather than an observer side, includes, for example, a parallax barrier scheme, a lenticular lens scheme, or a microlens array scheme.
[0063] In an embodiment, the lenticular lens 510 may be disposed in front of the 3D display 230, as illustrated in FIG. 5A. For example, the lenticular lens 510 may be formed of film or glass and attached in front of the 3D display 230. For example, pixels P.L. to be input to the left eye and pixels P.R. to be input to the right eye may be alternately arranged along a horizontal direction on the 3D display 230, and the lenticular lens 510 may provide optical discriminative directivity for the pixels P.L. to be input to the left eye and the pixels P.R. to be input to the right eye. In an embodiment, the 3D display 230 may separately provide different screens to the user's left eye L and right eye R by the lenticular lens 510 located in front of it.
[0064] In an embodiment, the parallax barrier 520 may be disposed in front of the 3D display 230, as illustrated in FIG. 5B. For example, the parallax barrier 520 may be attached in front of the 3D display 230, and the electronic device 101 may control the movement of the parallax barrier 520. For example, the pixels P.L. to be input to the left eye and the pixels P.R. to be input to the right eye may be alternately arranged along the horizontal direction on the 3D display 230, and screens may be separately provided to the left eye L and the right eye R through an aperture in a vertical grid pattern. In an embodiment, the 3D display 230 may separately provide different screens to the user's left eye L and right eye R by the parallax barrier 520 located in front of it.
[0065] Further, in an embodiment, the electronic device 101 may be formed in a glasses form and provided with separate displays (not shown) corresponding to the user's left eye and right eye, to induce binocular parallax. In an embodiment, the electronic device 101 may provide a 3D screen to the user by displaying different images or videos to the user's left eye and right eye.
[0066] In an embodiment, the electronic device 101 may display a 3D screen through the display area of the display (not shown) that displays screens corresponding to the user's two eyes, respectively, and move an object included in the 3D screen in the depth direction of the display (not shown).
[0067] The electronic device 101 according to an embodiment may implement virtual reality (VR) through the display area of the display (not shown). In an embodiment, the electronic device 101 may display a virtual object on the display area of the display (not shown).
[0068] The electronic device 101 according to an embodiment may implement augmented reality (AR) through the display area of the display (not shown). In an embodiment, the electronic device 101 may expose an external environment to the user through the display area of a transparent or translucent display (not shown). In an embodiment, the electronic device 101 may display a virtual object on the display area of the transparent or translucent display (not shown) such that it overlaps the external environment.
[0069] In an embodiment, the electronic device 101 may use the input interface (e.g., the input interface 250 of FIG. 2) which obtains a user input by sensing the movement of the user's hand through the camera sensor (e.g., the camera sensor 270 of FIG. 2) or by using the movement of a cursor through the input device (e.g., the input device 105 of FIG. 2).
[0070] In an embodiment, in response to a user input to a virtual object, the electronic device 101 may output a designated response based on a property of the object or a property of the user input.
[0071] In an embodiment, when the electronic device 101 is not capable of outputting the designated response based on the property of the object or the property of the user input in response to the user input to the virtual object, it may move the virtual object in the depth direction of the display (not shown).
[0072] FIG. 6 illustrates a 3D rendering space (view frustum) according to an embodiment of the disclosure.
[0073] Referring to FIG. 6, the 3D rendering space according to an embodiment may be a space defined by a camera (not shown) disposed for 3D rendering or the user's eyes L and R. In an embodiment, the electronic device 101 may render an object (not shown) located inside the 3D rendering space and display it on the 3D display (e.g., the 3D display 230 of FIG. 2). In an embodiment, the electronic device 101 may not render an object O that has left the 3D rendering space.
[0074] In an embodiment, when the position, angle, or size of the object O included in a 3D screen displayed on the 3D display changes and leaves the 3D rendering space, the 3D screen and/or the object may be clipped.
[0075] In an embodiment, the electronic device 101 may set a pyramid-shaped 3D rendering space clipped by two clipping planes. In an embodiment, the electronic device 101 may set a 3D rendering space based on the positions of the eyes L and R (or the position of a camera), a field of view (FOV), an aspect ratio w/h, and/or two clipping planes zNear and zFar.
[0076] In an embodiment, the display area 235 of the 3D display 230 may be included in the 3D rendering space. In an embodiment, the electronic device 101 may set the 3D rendering space to extend forward and backward of the display area 235 of the 3D display 230.
[0077] For example, the two clipping planes zNear and zFar of the 3D rendering space may include a first clipping plane zNear located in front of the display area 235 of the 3D display 230 and a second clipping plane zFar located behind the display area 235 of the 3D display 230. For example, the aspect ratio w/h of the 3D rendering space may match the aspect ratio w/h of the display area 235 of the 3D display 230. In an embodiment, the electronic device 101 may set the 3D rendering space based on the position of the user or the positions x, y, and z of the eyes L and R relative to the display area 235 of the 3D display 230.
[0078] In an embodiment, the electronic device 101 may obtain at least one value related to the positions of the user's eyes L and R from at least one sensor (e.g., the eye-tracking sensor 240 of FIG. 2) set to measure at least one value related to the positions of the user's eyes L and R. In an embodiment, the electronic device 101 may newly obtain at least one value related to the positions of the user's eyes L and R or newly set a 3D rendering space, based on satisfaction of a designated update condition. For example, the electronic device 101 may obtain at least one value related to the positions of the user's eyes L and R from at least one sensor according to a designated periodicity. For example, the electronic device 101 may be configured to update the position of the user or the positions of the user's eyes L and R, as the obtained at least one value related to the positions of the user's eyes L and R changes.
[0079] In an embodiment, the electronic device 101 may identify the position of the user or the positions of the user's eyes L and R based on the at least one value obtained from the at least one sensor 240, and set the 3D rendering space based on the identified position of the user or the identified positions of the user's eyes L and R.
[0080] The electronic device 101 according to an embodiment may divide the 3D rendering space into a front (positive) space of the display area of the 3D display 230 and a rear (negative) space of the display area of the 3D display.
[0081] The electronic device 101 according to an embodiment may identify whether an object (not shown) on a 3D screen displayed on the 3D display 230 is located in the front space of the 3D rendering space. In an embodiment, when the object (not shown) is located in the front space of the 3D rendering space, the electronic device 101 may identify whether a culling phenomenon occurs, in which the object (not shown) is partially clipped by leaving the 3D rendering space or a free display space (free zone) described later.
[0082] In an embodiment, the electronic device 101 may display a preview of the object O moved in the 3D rendering space through the 3D display 230 or 160 based on a user input.
[0083] In an embodiment, when the object (not shown) is located in the front space of the 3D rendering space, the electronic device 101 may provide a feedback related to the movement of the object corresponding to the user input.
[0084] In an embodiment, when the object O is located in the rear space of the 3D rendering space, the electronic device 101 may not identify whether the object O leaves the 3D rendering space or the free display space described later. Because the culling phenomenon occurring in the rear space of the 3D rendering space may be accepted by the user as a natural phenomenon, it may not be determined whether the culling phenomenon occurs. Accordingly, unnecessary computation may be skipped, and the rendering speed of the object (not shown) may be improved.
[0085] FIG. 7A illustrates a free display space and a restriction display space (restriction zone) inside a 3D rendering space according to an embodiment of the disclosure. FIG. 7B is a plan view of FIG. 7A.
[0086] Referring to FIGS. 7A and 7B, the electronic device 101 according to an embodiment may set the free display space inside the 3D rendering space. The electronic device 101 according to an embodiment may set a space outside the free display space within the 3D rendering space as the restriction display space. In an embodiment, the electronic device 101 may divide the 3D rendering space into the free display space and the restriction display space so that it may pre-detect that the object O is adjacent to the boundary of the 3D rendering space.
[0087] For example, the electronic device 101 may set a free display space having a boundary that is inwardly separated by a designated distance from the boundary of the 3D rendering space. For example, the electronic device 101 may set the free display space by applying a margin of a designated size inward into the 3D rendering space.
[0088] The electronic device 101 according to an embodiment may freely move, rotate, and/or scale the object O located inside the free display space.
[0089] The electronic device 101 according to an embodiment may identify whether at least a portion of the object O leaves the free display space in response to a user input. As the positions of the user's eyes L and R change, the electronic device 101 according to an embodiment may identify whether at least a portion of the object O leaves the free display space.
[0090] In an embodiment, when identifying that the at least portion of the object O leaves the free display space due to the user input, the electronic device 101 may provide a feedback related to at least one of rotation, movement, or reduction of the object O in response to the user input.
[0091] In an embodiment, the electronic device 101 may restrict the movement, rotation, enlargement, and/or reduction of the object O located at least partially in the restriction display space, or provide a feedback for the user input.
[0092] When identifying that the at least portion of the object O leaves the 3D rendering space or the free display space, the electronic device 101 according to an embodiment may determine the transformation type and/or transformation weight of the feedback to be provided in response to the user input.
[0093] FIG. 8A illustrates a state where the object O is rotated, moved, or enlarged so that it leaves the 3D rendering space according to an embodiment of the disclosure. FIG. 8B illustrates a state where images of the object O overlap due to enlargement or movement at or above a threshold according to an embodiment of the disclosure. FIG. 8C illustrates a state where the object O leaves the 3D rendering space according to the positions of the user's eyes L and R, according to an embodiment of the disclosure.
[0094] Referring to FIG. 8A, in the electronic device 101 according to an embodiment, the object O included in the 3D screen displayed on the 3D display 230 may be moved, rotated, enlarged, or reduced according to an input of a user U. For example, the 3D object O included in the 3D screen may be rotated, moved, or enlarged so that it leaves the 3D rendering space. When at least a portion of the object O is clipped outside the 3D rendering space in this way, the immersion of the user U in the object O displayed stereoscopically may be broken.
[0095] Referring to FIG. 8B, as the electronic device 101 according to an embodiment rotates, moves, or enlarges the object O by a threshold or greater, at least a portion of the object O may leave the 3D rendering space in the forward direction of the 3D display 230. When the at least portion of the object O is rotated, moved, or enlarged by the threshold or greater in the forward direction of the 3D display 230 in this way, the object O may appear to overlap in two images, which may break the immersion of the user U in the 3D displayed object O.
[0096] Referring to FIG. 8C, as the positions of the user's eyes L and R change, the electronic device 101 according to an embodiment may set the 3D rendering space differently. For example, when the user U moves outward from the display area relative to the 3D display 230, at least a portion of the object O located inside the 3D rendering space may leave the newly set 3D rendering space. When the at least portion of the object O is clipped outside the 3D rendering space in this way, the immersion of the user U in the 3D displayed object O may be broken.
[0097] FIG. 9 illustrates an embodiment of adjusting a moving speed based on a movement input for the object O in the electronic device 101 according to an embodiment of the disclosure.
[0098] Referring to FIG. 9, the electronic device 101 according to an embodiment may receive a movement input of the user U for the object O included in the 3D screen displayed on the 3D display 230. For example, the movement input of the user U for the object O may include a drag input or a sliding input for the object O.
[0099] In an embodiment, when the electronic device 101 receives the movement input of user U for the object O inside the free display space, it may move the object O displayed on the 3D display 230 in real time. For example, the electronic device 101 may move the object O proportionally by a distance x from position A to position B in response to a movement of y of a touch input or the input device inside the free display space.
[0100] The electronic device 101 according to an embodiment may identify whether at least a portion of the object O leaves the free display space due to the movement input of the user U. For example, the electronic device 101 may identify that an end portion of the object O leaves the free display space at position B.
[0101] When identifying that the at least portion of the object O leaves the free display space, the electronic device 101 according to an embodiment may adjust the moving speed of the object O according to the movement input of the user U. For example, the electronic device 101 may slow down the movement distance of the object O moving in response to the movement input of the user U. For example, the electronic device 101 may move the object O by a distance xx from position B to position C, in response to a relatively long movement of yy of the touch input or the input device.
[0102] When the input of the user U for the object O is a movement input in a direction parallel to the display area of the 3D display 230, the electronic device 101 according to an embodiment may adjust the moving speed of the object O according to the movement input of the user U.
[0103] Therefore, when at least a portion of the object O leaves the free display space, the user U may perceive that the movement of the object O is slowed down in response to the movement input, and may be induced to determine that the movement of the object O is difficult.
[0104] FIG. 10 illustrates an embodiment of moving the object O in a reverse direction of a movement input for the object O in the electronic device 101 according to an embodiment of the disclosure.
[0105] Referring to FIG. 10, the electronic device 101 according to an embodiment may receive a movement input of the user U for the object O included in the 3D screen displayed on the 3D display 230. In an embodiment, when the electronic device 101 receives the movement input of the user U for the object O inside the free display space, it may move the object O displayed on the 3D display 230 in real time. For example, the electronic device 101 may move the object O proportionally by a distance x from position A to position B in response to a movement of y of a touch input or the input device from position 1 to position 2 inside the free display space.
[0106] The electronic device 101 according to an embodiment may identify whether at least a portion of the object O leaves the free display space in response to the movement input of the user U. For example, the electronic device 101 may identify that the end portion of the object O leaves the free display space at position B.
[0107] When identifying that at least a portion of the object O leaves the free display space, the electronic device 101 according to an embodiment may move the object O in the reverse direction of the movement input for the object O. For example, the electronic device 101 may move the object O in the direction reverse to the direction of the movement input of the user U.
[0108] For example, the electronic device 101 may move the object O from position B to position C in response to a movement of y of the touch input or the input device from position 1 to position 2, and then move the object O from position C to position B in the reverse direction of the movement. For example, the electronic device 101 may move the object O by a distance xx which is relatively shorter than the distance x that the object O moves from position A to position B in response to the movement of y of the touch input or the input device from position 1 to position 2 inside the free display space.
[0109] The electronic device 101 according to an embodiment may move the object O to a designated position (e.g., position B where the end portion of the object O leaves the free display space) in the reverse direction of the movement by applying a bounce back effect, like the object O being bounced in the reverse direction, in response to the movement of y of the touch input or the input device.
[0110] The electronic device 101 according to an embodiment may identify a material property of the object O and, when the identified material property of the object O is an elastic body, move the object O in the reverse direction of the movement input of the user U.
[0111] In an embodiment, the material property of the object O may be variously applied, such as plastic, wood, cement, or stone. For example, the material property of the object O may be an elastic body having elasticity, such as rubber, or a magnetic body that reacts to magnetism, such as metal.
[0112] Therefore, when at least a portion of the object O leaves the free display space, the user U may be induced to determine that the movement of the object O is difficult by the object O moving in the reverse direction of the movement input.
[0113] FIG. 11 illustrates an embodiment of moving the object O to a designated position based on a movement input for the object O in the electronic device 101 according to an embodiment of the disclosure.
[0114] Referring to FIG. 11, the electronic device 101 according to an embodiment may receive a movement input of the user U for the object O included in the 3D screen displayed on the 3D display 230.
[0115] In an embodiment, when the electronic device 101 receives the movement input of the user U for the object O inside the free display space, it may move the object O displayed on the 3D display 230 in real time. For example, the electronic device 101 may move the object O proportionally by a distance x from position A to position B in response to a movement of y of a touch input or the input device inside the free display space.
[0116] The electronic device 101 according to an embodiment may identify whether at least a portion of the object O leaves the free display space due to the movement input of user U. For example, the electronic device 101 may identify that the end portion of the object O leaves the free display space at position B.
[0117] When identifying that the at least portion of the object O leaves the free display space, the electronic device 101 according to an embodiment may move the object O to a designated position according to the movement input of the user U. For example, the designated position may be a position moved in the forward direction (e.g., a parallel direction or the same direction) of the movement input of the user U. For example, the electronic device 101 may move the object O from position B to position C which is moved by xx in response to a movement of yy of the touch input or the input device.
[0118] The electronic device 101 according to an embodiment may set the designated position as the boundary of the 3D rendering space spaced apart in the forward direction of the movement input of the user U.
[0119] In an embodiment, when identifying that at least a portion of the object O leaves the free display space, the electronic device 101 may move the object O to the designated position by applying a snap effect, like sticking to a magnet, in response of the movement input of the user U.
[0120] The electronic device 101 according to an embodiment may identify the material property of the object O and, when the identified material property of the object O is a magnetic body, move it to a designated position corresponding to the forward direction of the movement input of the user U.
[0121] Therefore, when at least a portion of the object O leaves the free display space, the user U may perceive that the object O moves to the designated position according to the movement input, and may be induced to recognize a limit point of the movement of the object O.
[0122] FIG. 12A illustrates an embodiment of displaying a boundary plane according to a movement of the object O according to an embodiment of the disclosure. FIG. 12B illustrates an embodiment of providing a haptic feedback according to a movement of the object O according to an embodiment of the disclosure.
[0123] Referring to FIG. 12A, when the electronic device 101 according to an embodiment snaps the object O to a designated position corresponding to the forward direction of a movement input or bounces the object O in the reverse direction of the movement input in response to the movement input of the user U for the object O, it may provide an additional visual effect to enhance the awareness of the user U.
[0124] In an embodiment, when the electronic device 101 snaps the object O to the designated position corresponding to the forward direction of the movement input or bounces the object O in the reverse direction of the movement input, it may display a virtual plane at the designated position. In an embodiment, the electronic device 101 may display a virtual plane 1200 on a boundary surface of the 3D rendering space corresponding to the forward direction of the movement input for the object O. In an embodiment, the electronic device 101 may apply a grid effect that displays a grid on the virtual plane 1200.
[0125] Referring to FIG. 12B, when the electronic device 101 according to an embodiment snaps the object O to a designated position corresponding to the forward direction of a movement input or bounces the object O in the reverse direction of the movement input in response to the movement input of the user U for the object O, it may provide a haptic effect (e.g., tactile effect) to enhance the awareness of the user U.
[0126] In an embodiment, when the electronic device 101 snaps the object O to the designated position corresponding to the forward direction of the movement input or bounces the object O in the reverse direction of the movement input, it may provide a haptic effect that generates mechanical vibration or electrical stimulation in the electronic device 101 (e.g., haptic module 179 of FIG. 1) or the input device.
[0127] FIG. 13 illustrates an embodiment of enlarging the object O according to an enlargement input for the object O in the electronic device 101, according to an embodiment of the disclosure.
[0128] Referring to FIG. 13, the electronic device 101 according to an embodiment may receive a size change input of the user U for the object O included in the 3D screen displayed on the 3D display 230.
[0129] In an embodiment, when the electronic device 101 receives an enlargement or reduction input of the user U for the object O inside the free display space, it may enlarge or reduce the object O displayed on the 3D display 230 in real time. For example, the electronic device 101 may enlarge the object O in response to an enlargement input via a touch input or the input device, inside the free display space.
[0130] The electronic device 101 according to an embodiment may identify whether at least a portion of the object O leaves the free display space due to the enlargement input of the user U. For example, the electronic device 101 may identify that an end portion B of the object O leaves the free display space.
[0131] When identifying that at least a portion of the object O (e.g., the end portion B of the object O) leaves the free display space, the electronic device 101 according to an embodiment may reduce the object O so that the object O is located within the free display space. For example, the electronic device 101 may enlarge or reduce the object O based on a center point C of the object O.
[0132] Therefore, when at least a portion of the object O leaves the free display space, the user U may perceive that the object O is reduced according to to the enlargement input for the object O, and may be induced to recognize the limit of the enlargement of the object O.
[0133] FIG. 14 illustrates an embodiment of rotating the object O according to a rotation input for the object O in the electronic device 101, according to an embodiment of the disclosure. FIG. 15 illustrates an embodiment of moving a rotation axis of the object O according to a rotation input for the object O in the electronic device 101, according to an embodiment of the disclosure.
[0134] Referring to FIGS. 14 and 15, the electronic device 101 according to an embodiment may receive a rotation input of the user U for the object O included in the 3D screen displayed on the 3D display 230.
[0135] In an embodiment, when the electronic device 101 receives the rotation input for the object O inside the 3D rendering space, it may rotate the object O displayed on the 3D display 230 in real time. For example, inside the 3D rendering space, the electronic device 101 may rotate the object O in response to a rotation input via a touch input or the input device. For example, the electronic device 101 may rotate the object O using the center point of the object O as a rotation axis, axis 1.
[0136] In an embodiment, the electronic device 101 may identify whether at least a portion of the object O leaves the 3D rendering space based on the rotation input of the user U for the object O. For example, as the object O is rotated by a rotation angle B based on the rotation input of the user U, the electronic device 101 may identify that at least a portion of the object O (e.g., an end portion of the object O) leaves the 3D rendering space.
[0137] In an embodiment, the electronic device 101 may rotate the object O in the reverse direction of the rotation input of the user U. In an embodiment, the electronic device 101 may rotate the object O by a rotation angle C at which at least a portion of the object O that moved outward from the 3D rendering space due to the rotation of the object O is pulled back inside the 3D rendering space. For example, the electronic device 101 may rotate the object O using the center point axis 1 of the object O as a rotation axis.
[0138] In an embodiment, the electronic device 101 may move a rotation axis, axis 2 of the object O toward the at least portion of the object O that leaves the 3D rendering space. In an embodiment, along with the movement of the rotation axis, axis 2 of the object O, the electronic device 101 may rotate the object O by the rotation angle C at which the at least portion of the object O that moves outward from the 3D rendering space due to the rotation of the object O is pulled back inside the 3D rendering space. Accordingly, the rotation range and/or rotation radius of the object O may be reduced.
[0139] Therefore, when at least a portion of the object O leaves the 3D rendering space, the user U may perceive that the object O is rotated in the reverse direction according to to the rotation input for the object O, and may be induced to recognize the limit of the rotation of the object O.
